Looking into the numbers a couple if months ago I was surprised how little it costs to stop climate change.

On the order of 100-200 trillion USD. Which is roughly 100-200% of global yearly GDP. Or 2-5% of yearly GDP until 2050. This could well be provided by printing money at all the federal reserve banks.

This investment will likely bring in a positive return on investment because it reduces the negative climate impacts.

Without such investments the downstream costs in climate change adaptation will be very expensive

If you read Drawdown, you'll see that it doesn't cost money to stop climate change, it saves money.

Of course stopping climate change will save in the long run. The critical question is who should spend the money now to save money later. That is the crux of the free rider problem.
